The CPU 10a is a control unit that performs control related to execution of a program stored in the RAM 10b or the ROM 10c, calculation of data, and processing. The CPU 10a is a computing unit that executes a program (operation analysis program) for analyzing time-series data relating to a job performed by an operator to generate operation data, and controlling the operation data and an evaluation thereof to be displayed on a display unit. The CPU 10a receives various data from the input unit 10e or the communication unit 10d, and displays the calculation result of the data on the display unit 10f or stores the calculation result in the RAM 10 b.
The RAM 10b is a portion of the memory section in which data can be rewritten, and may include, for example, a semiconductor memory element. The RAM 10b can store data such as programs and operation data executed by the CPU 10 a. These are examples, and data other than these may be stored in the RAM 10b, or a part of them may not be stored.
The ROM 10c is a portion of the storage section from which data can be read, and may include, for example, a semiconductor memory element. The ROM 10c may store, for example, an operation analysis program or data not to be rewritten.

These physical configurations are examples, and may not necessarily be independent configurations. For example, the operation analysis device 10 may include a Large-Scale integrated circuit (LSI) in which the CPU 10a is integrated with the RAM 10b or the ROM 10 c.
Action example 3
Fig. 4 is a diagram showing operation data generated by the operation analysis device 10 of the present embodiment. In this figure, an example of the left-hand motion data D1 and the right-hand motion data D2 is shown. The characters t1 to t12 shown in the figure indicate time points arranged in time series.
The left-hand motion data D1 and the right-hand motion data D2 include a column of "element motion" indicating the type of element motion, a column of "start time" indicating the start time of the element motion, and a column of "end time" indicating the end time of the element motion.
For example, regarding the left-hand motion data D1, the "element motion" having the beginning "t 2" and the end "t 4" is "grab". In the right-hand motion data D2, "element motion" having a start time of "t 1" and an end time of "t 3" is "grasping". At this time, it shows: the gripping action starts with the right hand, then with the left hand, and then the right hand gripping ends and the left hand gripping ends.
In the right-hand operation data D2, "element operation" having the start time "t 7" and the end time "t 8" is "NA", indicating that no operation related to the job is performed. Note that "element operation" indicates "NA" and includes an operation that the operator a stops or performs an operation unrelated to a predetermined element operation.
Fig. 5 is a diagram showing an example of a screen on which display control is performed by the operation analysis device 10 according to the present embodiment. In this example, the motion analysis device 10 evaluates the left-hand motion data D1 and the right-hand motion data D2 shown in fig. 4, and displays the evaluation and motion data together.
For example, by means of a graph representing the grip: the gripping operation is performed with the right hand from time t1 to time t3, and the gripping operation is performed with the left hand from time t2 to time t 4. Here, from time t2 to time t3, the grasping is performed in parallel with the right hand and the left hand. The motion analysis device 10 detects that the element motion of the grasping is executed by the right hand and the left hand in parallel, and the motion is evaluated. In response to this comment, a comment "two-handed job", a circle icon, and an icon representing the two-handed job are displayed. Such icons are also displayed from time t4 until time t 5. From time t4 to time t5, the element operations of conveyance are executed in parallel by the right hand and the left hand.
On the other hand, from time t7 to time t8, neither the right hand nor the left hand performs the operation related to the job. In other words, the right hand and the left hand are NA for the motion data from time t7 to time t 8. The operation analysis device 10 gives a bad comment when neither the right hand nor the left hand performs an operation related to a job. Corresponding to this comment, "useless" is displayed, crossed icons and icons representing the confounding appearance.
Fig. 6 is a flowchart of a first example of the display control process executed by the motion analysis device 10 according to the present embodiment. The first example of the display control processing is processing for controlling the display unit 10f to display the operation data.
First, the operation analysis device 10 reads flow data from the storage unit 13 (S10). Here, the flow data is operation data indicating an ideal flow relating to the work of the worker a. The flow data may be read from the storage section 13, but may also be read from an external storage device.
Next, the motion analysis device 10 repeatedly executes the following processing S111 and processing S112 until the end of the flow data (S11). The motion analysis device 10 sets a display width in accordance with the execution time from the start time to the end time of the element motion (S111), and displays data in left alignment while dividing the periods corresponding to different element motions (S112).
By executing the first example of the display control processing, the flow data is displayed on the display unit 10f in time series and with a width corresponding to the execution time.
Fig. 7 is a flowchart of a second example of the display control process executed by the operation analysis device 10 according to the present embodiment. A second example of the display control processing is an example of processing that is executed after the first example of the display control processing and that controls to display the evaluation of the element action together with the action data.
The motion analysis device 10 reads the motion data of the right hand (S12), and reads the motion data of the left hand (S13). It is to be noted that the right-hand operation data and the left-hand operation data may be read in any order.
Next, the motion analysis device 10 repeatedly executes the following processing S141 to S145 until the end of the motion data (S14). The motion analysis device 10 sets a display width in accordance with the execution time from the start time to the end time of the element motion (S141), and displays data in left alignment by dividing the periods corresponding to different element motions (S142).
The motion analysis device 10 evaluates the element motions performed by both hands (S143), and displays an icon indicating the evaluation along the data if the evaluation related to the element motions is a good evaluation or a bad evaluation (S144: yes) (S145). On the other hand, if the evaluation on the element operation is not good or bad (S144: no), the operation analysis device 10 executes the next process without displaying the icon.
By executing the second example of the display control processing, the right-hand and left-hand motion data are displayed on the display unit 10f in time series and with a width corresponding to the execution time, and an icon indicating the evaluation is displayed on the display unit 10f together with the motion data.
Fig. 8 is a flowchart of a third example of the display control process executed by the operation analysis device 10 according to the present embodiment. A third example of the display control processing is an example of processing that is executed after the first example of the display control processing and that controls to change the display form of the operation data in accordance with the evaluation of the element operation.
The motion analysis device 10 reads the motion data of the right hand (S12), and reads the motion data of the left hand (S13). It is to be noted that the right-hand operation data and the left-hand operation data may be read in any order.
Next, the motion analysis device 10 repeatedly executes the following processing S141 to S145 until the end of the motion data (S14). The motion analysis device 10 sets a display width in accordance with the execution time from the start time to the end time of the element motion (S141), and displays data in left alignment by dividing the periods corresponding to different element motions (S142).
Then, the motion analysis device 10 evaluates the element motions performed by both hands (S143), and if the evaluation regarding the element motions is a good evaluation or a bad evaluation (S144: yes), changes the display form of the motion data according to the evaluation (S145). For example, the motion analysis device 10 may display the motion data corresponding to the element motion with a high score in blue, and display the motion data corresponding to the element motion with a low score in red. On the other hand, if the evaluation on the element operation is not good or bad (S144: no), the operation analysis device 10 does not change the display mode of the operation data, but displays the operation data in black, for example, and executes the next processing.
In the third example of the display control process, the motion data of the right hand and the left hand are displayed on the display unit 10f in time series and with a width corresponding to the execution time, and the motion data is displayed on the display unit 10f in a display form corresponding to the evaluation of the element motion.
